Guyson's Orbit 600 RPF (Residual Particle Flush) system for removal of residual powders from AM trabecular structures.
Guyson International, the UK headquartered manufacturer of industrial finishing equipment, has unveiled its latest machine designed for removing residual powders from additively manufactured medical implants.
The Guyson Orbit 600 RPF (Residual Particle Flush) focuses specifically on removing trapped powder inside orthopaedic trabecular structures, typically produced by selective laser sintering, selective laser melting or electron beam melting, which aid the interlocking human bone growth into the implant.
The Orbit 600 RPF builds on Guyson’s Orbit 600 rotary basket spray wash unit which is fitted with a 100-litre insulated tank and hot spray flushing facilitated through a high flow rate and pressure pump fitted with viton seals. The machine offers directed jets for powerful component flushing followed by compressed air-wash. During operation, implants are individually or batch loaded on none contaminating fixtures presenting the work piece to the directed flushing jets in close proximity to the trabecular surface to ensure thorough powder removal.
Guyson’s Managing Director, Mark Viner, said: “This new [Guyson Orbit 600 RPF] unit adds to the already extensive portfolio of Guyson products provided for the 3D print/additive manufacturing market. This includes our Euroblast Ex range of ATEX certified blast cabinets for surface finishing exotic metal AM parts, often used in the aerospace and medical markets. The Guyson PRS (Powder Recovery System), which is an automated post processing system, specifically for EBM additive builds, and uses tried and trusted robotic blasting methodology to reveal components and manage the resultant powder in a highly contained blast system, and our ‘Kerry’ branded range of ultrasonic baths and tanks for 3D printed fused deposition modelling (FDM) support removal."
Editor's note: The Guyson Orbit 600 RPF was originally launched under the brand name 'Powder Flush', but underwent a rebrand shortly after its release to market. This article was edited in March 2022 to reflect that rebranding.
